Answer:
A. <em>6.12</em>
Step-by-step explanation:
if you mark up 2.00$ with 240% you get 6.80 $

Answer:
3.3333 repeating
Step-by-step explanation:
This is the answer because if you take 100 percent or just 100, and divide that by the number of coins there are ( which there are 3 in this case) then you would get your answer which is 3.3333 repeating...
Hope this answer helps
Answer:
x=15 cm
Step-by-step explanation:
The two triangles in the diagram are:
ABC and BDC
First we have to find the third side (hypotenuse) of BDC so that we can use it to find the value of x.
Hypotenuse is the largest side of a triangle which is usually in front of the right angle.
So in BDC

Applying Pythagoras theorem:

Solving for triangle ABC

Applying Pythagoras theorem

Hence,
x=15 cm
40% of 250 is 250 × 40/100 = 25 × 4 = 10
